SCM & Trapezius Atrophy

I have extreme atrophy of the R SCM muscle as well as Trapezius.  I visited a Neurologist and did all the testing and was told that I might have some sort of condition with my Spinal Accessory Nerve.  I also have winging of the scapula.  Along with that I have what looks like a right vocal cord paralysis and my larnyx seems to be shifted over as well.  Both of these make it very hard for me to swallow. Can anyone give me any advice or does anyone have any knowledge of this.  I have had several MRI's and will have one on my brain here in a few days.  The lab technician reports that I had radical neck dissection, which I never have but basically I have the symptoms of that procedure.  I am going to see a specialist in the field of Neurology but I was wondering if anyone could give me some information that might help get to the bottom of what is going on with me.
